CHICAGO, USA -- The CST-01 watch, made by the Chicago-based firm Central Standard Timing, is thinner than a credit card - just 0.8mm thick - and shows the time on an electronic ink display; the world's thinnest watch has a 0.5mm flexible electronic component built-in and a Thinergy Micro-Energy Cell battery that can be charged in 10 minutes and has a lifetime of 15 years, setting the world record for the thinnest watch,
according to the World Record Academy: www.worldrecordacademy.com/.

The Guinness world record for the longest chain of watches consisted of 1,382 Swatches buckled together in Oeiras Parque, Lisbon, Portugal.

Guinness World Records also recognized the world record for the smallest watch movement, sety by Cal.G720, developed and manufactured by Citizen Watch Co., Ltd. (Japan) in 2002, which measures 30 mm² (0.046 in²) in surface area and 73 mm³ (0.004 in³) in volume. Watch movement means machine parts of a watch except for exterior parts, such as a case, a dial and hands. Its full dimensions are 5.0 mm x 6.0 mm x 2.5 mm.

According to Central Standard Timing, the patent-pending CST-01 is assembled by laminating thin, flexible components into a 0.5mm pocket etched into a single piece of flexible stainless steel.
This is different from traditional digital watches, which typically use the same chassis used for analog watches.

The CST-01 also uses an embedded Thinergy Micro-Energy Cell that charges in 10 minutes from an external dock and has a lifetime of 15 years. All CST-01 watches are planned to be assembled in the USA.

The battery can be recharged 10,000 times and each charge will last about 30 days.

Central Standard Timing was founded by engineers Dave Vondle and Jerry O'Leary, both formetly of successful design outfit IDEO.
